The atomic weight of carbon dioxide is about 12.011 + 15.999 + 15.999 = 44.009.
44.009 grams of CO2 = 1 mole of CO2 CO2 = Carbon dioxide
25 ÷ 44.009 ≈ 0.568
About 0.568 moles of CO2
The partial pressure of Ne is 1.06 atm. The answer is a. 1.1 atm
To get the concentration of the second solution let us use the following formulae
C1V1=C2V2 where C1 is concentration of first solution and V1 is the volume of solution first solution. on the other hand C2 is the concentration of second solution and V2 is the volume of second solution.
therefore
0.8×2=(2+10)×C2
1.6 =12×C2
1.6/12=C2
C2 = 0.1333mg/mL
The density of the sample : 0.827 g/L
<h3>Further explanation</h3>
In general, the gas equation can be written

where
P = pressure, atm , N/m²
V = volume, liter
n = number of moles
R = gas constant = 0.082 l.atm / mol K (P= atm, v= liter),or 8,314 J/mol K (P=Pa or N/m2, v= m³)
T = temperature, Kelvin
n= 1 mol
MW Neon = 20,1797 g/mol
mass of Neon :

The density of the sample :

or We can use the ideal gas formula ta find density :

Answer:
equals
